PRR I-1 Decapod 2-10-0

History:  Class 2-10-0 Decapods were not a favorite with most railroads; they were rough-riding, but the Pennsylvania Railroad was satisfied with what they saw. The Decapods were tough, had enormous strength, and could be depended on for carrying goods up large mountain slopes. It was said that wherever there were hills, there were usually decapods not far away.

The first Altoona-built 2-10-0 locomotive emerged from Juniata's erecting shop in December of 1916. It was designed by the genius of Alfred W Gibbs and Axel S Vogt. The I-1 engine could travel up the Allegheny Mountains of Pennsylvania faster than other engines in use built prior to this one. A total of 598 I-1s were built. 123 I-1s were built at the Juniata Shops and 475 at the Baldwin Shops. The order for 475 at the Baldwin Shops was the largest order ever for a single class of power!

By 1924, I1s were tearing up the railways. They were regarded as the standard heavy freight hauler of the railroad, achieving speeds of up to 50 miles per hour. They replaced three smaller types of engines: the Consolidations, Mikados, and USRA Santa Fe's.

Some specifications of the I-1 included a boiler that was the largest applied to any Pennsylvania Railroad class up to 1916. The boiler was fed by mechanical stokers and required 250 pounds of steam pressure in its 30 1/2" x 32" cylinders to operate. The total engine weight was 386,100 pounds and had tractive force of 90,024 pounds.

The first I-1, Locomotive No. 790 displayed Juniata Shop badge plate No. 3165. It out-performed the L-1 class 2-8-2 by forty-one percent more horsepower, while utilizing twelve percent less steam. It could travel great distance, powered by only a small amount of steam.

Over a span of many years, the I-1 engines were broken down into subdivisions: the I-1sa and Class I-1s. The I-1sa class had 489 locomotives and the I-1s class had 109 locomotives.

The most notable feature of the decapods was the twin bulky air reservior tanks riding up front on the pilot deck. They were not on the original locos, but were implemented later.

One of the last and most famous runs of the I-1s was the transporting of iron ore out of Northumberland, Pennsylvania. They carried nine thousand tons of ore over the Shamokin Branch to an interchange in the Lehigh Valley.

The Deluxe Kit Includes:  The locomotive and tender complete kit, a painted engineer and fireman, and all of the "Super Detail Kit" parts. In addition, the boiler & tender body have been pre-drilled to enable installation of all the "Super Detail Kit" parts and the valve gear has been assembled.  Please note that some holes may need to reamed to fit the posts on some parts.

In addition we have a painted engineer and fireman, a smoke unit kit and assemblies available as optional equipment to compliment your kit-building needs.
